    - Main form doesn't repaint until mouse moved I've got a c# desktop app with various menu items that display modal dialogs for changing app settings, etc.. Standard stuff. After a particular dialog is closed, the main form doesn't repaint the area that was covered by the child form until the user moves the mouse. I can't see how this one form is different from the others, or what I may have done to prevent the main form from repainting. Any suggestions on things to check would be appreciated.

    - Distinguish TerminalServer session versus XP RDP session vb.net 2005 windows app with .net framework 2.0 On Windows XP, System.Windows.Forms.SystemInformation.TerminalServerSession is returning True when connected to Windows XP via remote desktop using the /console switch. I confirmed in an XP running in VirtualPC 2004 ... Task Manager (users tab) that the session shows as "RDP-Tcp#blah" rather than console. Is this expected behavior? If this is expected behavior, how does an application distiguish if it is running in terminal services versus a windows xp remote desktop session?

    - PostScript font support in GDI+? Is support for PostScript fonts planned, or possible through a workaround? Only TrueType fonts and OpenType fonts containing TrueType outlines can be picked for WinForms forms and controls; Type 1 and OpenType with Postscript outlines don't show up in the font selector. I'm working on a kiosk app for which part of the layout (background etc.) was designed by a graphic agency, who used a font from Adobe for textual elements. Now I'm expected to use the same font in software, but it's only available in PS and OpenType-PS. I did find a close look-alike in TTF format at URW++, but even I (not a graphic designer by art&heart) found some small differences, and I'd like to have the exact same typeface. There are tools that convert PS to TT outlines, but the results look so bad (choppy, pixelated) that they're useless for all but very large font sizes. Funny though: those PS-to-TTF converted fonts look just perfect under Linux, it's only under Windows that they get that choppy look. [I'm on Vista now, I haven't tried how they look on XP.] Tag: Need example of custom combobox inside DataGridView Tag: 117343

    - Datagridview conditional formatting using separate column Hi, I want to conditionally format a column in a datagridview according to the value in a different of my datasource. So if col 1 is true, then display col 2 in a different colour. I know that I can use the cell formatting event if I want to conditionally format the cell according to the value in that same column but is that the best method to use if I'm using a different column for the condition? Is this the best way of doing it, or is there something better? In cell formatting event... if dg.columns(e.columnindex).datapropertyname="ConditionColumn" then if e.value=conditionvalue then dim cell as datagridviewcell=dg(hard-coded column number, e.rowindex) cell.style.... do whatever formatting required end if end if Would be a bit of a kludge having to hard code the 'target' column number but I would actually replace that with a find on the datacolumns of the grid. In my case, I don't actually need the column that is being looked at for the condition on the grid. Does it HAVE to be there? Problem there is that if I add it and make it invisible then the formatting event doesn't kick in. Tag: Need example of custom combobox inside DataGridView Tag: 117339

    - Problems hosting a custom control / cell / column in a DataGridVie I'm having trouble hosting a custom control in one of the columns of a DataGridView object. The custom control is a multi-column combo box, which behaves almost identical to ComboBox, except that it shows multiple data columns when dropping down, similar to old MS Access style combos. The MultiColumnComboBox control can be found here: http://www.edneeis.com/control.aspx?ID=7 Based on the info in this article (http://msdn.microsoft.com/en-us/library/7tas5c80.aspx), and a little experimenting, I have it basically working. The control is being shown as a combo box in the data grid, it is being bound correctly, and is displaying properly. To get that far, I had to create a a hosting DataGridViewEditingControl control (implementing the IDataGridViewEditingControl interface), a DataGridViewComboBoxCell cell, and a DataGridViewComboBoxColumn specific to the new control. The one issue I'm having is with the drop-down event. I keep getting the following exception: Object reference not set to an instance of an object at System.Windows.Forms.DataGridViewComboBoxCell.ComboBox_DropDown(Object sender, EventArgs e) at System.Windows.Forms.ComboBox.OnDropDown(EventArgs e) at System.Windows.Forms.ComboBox.WmReflectCommand(Message& m) at System.Windows.Forms.ComboBox.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.SendMessage(HandleRef hWnd, Int32 msg, IntPtr wParam, IntPtr lParam) at System.Windows.Forms.Control.SendMessage(Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.Control.ReflectMessageInternal(IntPtr hWnd, Message& m) at System.Windows.Forms.Control.WmCommand(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam) at System.Windows.Forms.NativeWindow.DefWndProc(Message& m) at System.Windows.Forms.Control.DefWndProc(Message& m) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ComboBox.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at WindowsApplication2.Program.Main() in C:\Documents and Settings\jarmstrong\My Documents\Visual Studio 2005\Projects\Solution1\WindowsApplication2\Program.cs:line 17 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() DataGridViewComboBoxCell.ComboBox_DropDown is hidden from me, so I'm not sure what's going on.

    - DataGridView bound to BindingList<myObj> -- how to update immediately when they click a checkbox? I have a DataGridView bound to a BindingList<myObj>. In my DGV I have two checkbox columns. Right now, the user can check these, and if he clicks on another row or clicks on one of the buttons of the form, it will fire the EndEdit event, in which I have embedded a Save(). Is there a way to get it to save when they click on it, rather than waiting for the row to lose focus? I'm also going to have to make one of the textbox columns editable, so will the same solution work for that case as well? Thanks, RobinS.

    - Automating interactions with a web site Consider the following scenario: 1) User goes to a web site (.aspx page) and logs in 2) User enters various values in controls, clicking on NEXT buttons to go to a sequence of pages, until they get to a page that displays, among other things, a table showing 10 rows, each with a checkbox at the far left (i.e. first column). In addition, at the bottom of the table, there are little "links" that can be clicked on to go to the next/prior page, showing the next/prior ten results in a table. Lastly, in case it helps, there is, to the right of the "links", a text box in which the user can type a specific "page" of results to go to. NOTE: Unfortunately, the little "links", and Go To text box, slightly move from page to page, making mouse movement/click recording/playback not a viable option. 3) User puts check mark in all ten checkboxes, then clicks on link to go to next page of results. 4) After user has clicked on a total of 1,000 checkboxes (i.e. 100 pages' worth), they are done (for purposes of this discussion). What I want to do is automate Step 3 above 100 times. So, what I'm imagining is having a Windows form, with a web browser control on it that brings the user to the initial website. Then, the user would do stuff outlined in Step 2. Lastly, there'd be a button on the form (below the web browser control somewhere) that the user could click on to perform Step 3 100 times. Then, the user could just interact with the web browser again, clicking on whatever they need to click on. Is there a way to do something like this?

    - RichTextBox very slow I'm using a RichTextBox in a protocol analyser I'm developing. However as the amount of data gets large, e.g. 500000 lines, the control becomes very slow. For example if I load in a saved file it can take 30 seconds just to transfer data from a StringBuilder to the RichTextBox, even with updates turned off with WM_SETREDRAW. Also I highlight a line when the users clicks on it and this can be slow, as can be highlighting all instances of a string match. Is there any way to make actions like adding text to a RichTextBox or highlighted portions of text any faster? TIA, KK Tag: Need example of custom combobox inside DataGridView Tag: 117325

    - Application Settings and Form Location & Size I'm trying to use Application Settings with From Location & Size. I have created the property binding from the Designer in Visual Studio. ClientSize = MainFormClientSize Location = MainFormLocation I also have the following code: private void MainForm_FormClosing(object sender, FormClosingEventArgs e) { Properties.Settings.Default.MainFormClientSize = this.ClientSize; Properties.Settings.Default.MainFormLocation = this.Location; Properties.Settings.Default.Save(); } The code seems to work fine. I can start the application, change the size and location and close the application. And the next time I open the application, the size and location is correct from the last time the application was closed. But something strange happens if I try to minimize and restore the application. If I already have a size and location saved, do a minimize and restore, then the initial default value are set on the form. Do I need additional code to addresse minimize / restore scenarioes ?

    - TB_HITTEST? OK, still trying to figure out how to determine which tray icon button was pressed. I'm at the point where if I can just get TB_HITTEST to return valid data then I should be in good shape. My question is can I use TB_HITTEST given the hwnd of the tray toolbar window and the client coordinates of the tray button? Doing so always seems to yield -10 or there abouts. I believe this reflects the total count of buttons added vs. the current count. Is there some trick to getting TB_HITTEST to work when I'm sending to the tray window??? -- Grant Schenck Tag: Need example of custom combobox inside DataGridView Tag: 117321

    - Play Medai Whilst Updating Tags and FileName Hi All, I'm developing a small utility which will allow me to take my ever growing list of Mp3's and update the tags and cover art to upload to my Mp3 player.Most of my mp3's don't have any tags to go on, and some don't even have filenames to indicate what they are. To this end I'm developing and application that will let me browse a list of mp3 files, and one by one: 1) Let me play the mp3 (and provide transport controls to skip around), so I can identify the track / artist and at least start to search out the detail. 2) Search for the track information using MusicBrainz web server (done this bit already). 3) Get any artwork from Amazon Web Service (done this bit already). 4) Write the tag information away and the art work to the mp3 file. 5) Rename the file [Artist] - {TrackName].mp3. I don't have any experience using media controls - so I wondered how I would go about playing an mp3 in a WindowsForm, but still be able to write to the underlying file and rename it? Is there any way I can load the file into memory and play it from there? Alternately I could allow the user to search out the details and then at the point of saving - stop the playback.

    - How to fix the AutoGenerateColumns I was also being driven crazy by this problem of reappearing columns in the designer even though I had sub classed the DataGridView control and set base.AutoGenerateColumns = false in the constructor. After analysing ones that seemed to be OK vs ones that were having the problem, I found the corruption to be in the resx file for the datagridview. At the bottom of the file (open with an xml editor), there will be a number of <metadata > elements. Keep the one for your binding source and delete all the ones for the columns. Now regenerate your solution and then try re-opening your designer. If you are as lucky as me, then your problem should have disappeared. Good Luck.

    - Progress bar sometimes refuses to refresh (but works OK with DoEve I have a .NET 3.0 (VS2005) Winform app. The UI invokes a long-running BRL process (synchronously, on the same thread). The BRL raises events periodically to tell the UI to update a progress bar. Works OK, most of the time. But if the user does something as simple as clicking on the form, the update of the progress bar stops. I found that calling DoEvents (rather than just doing a Refresh) in the event handler that updates the Progress bar "fixes" the problem. But I've read posts saying that DoEvents is evil. And I can see why. But simply doing a Refresh in my event handler doesn't suffice. So is there another way ? (short of reworking the app to run the BR process on a separate thread...which introduces a different can of worms) Here's the event handler in the UI which exhibits the problem. Private Sub ProgressEventRaised(ByVal sender As Object, ByVal e As ProgressEventArgs) If e.recordsProcessed > Me.uiProgressBar.Maximum Then Me.uiProgressBar.Value = Me.uiProgressBar.Maximum Else Me.uiProgressBar.Value = e.recordsProcessed End If Me.Refresh End Sub ===> Replacing Me.Refresh with Application.DoEvents "fixes" it. <=== BTW: testing InvokeRequired and re-invoking the event handler doesn't fix the problem either: If Me.a-control-on-the-form.InvokeRequired Then Dim d As New ProgressEventCallback(AddressOf ProgressEventRaised) Me.Invoke(d, New Object() {sender, e}) Exit Sub End If But since my UI and BR code is running on the same thread, I would have been surprised if doing this helped.

    - Wrong size of UserControl Hello I have a UserControl sized to 100; 200 When I drop it in my form the initial size is 100;200 (as I prefer). Then I decided to change the size of my UserControl to 200;200 but although I have not set any value to the size of the dropped control in my form, recompiling the project does not affect the new size of the user control in my form. Surprisingly if I reset the Size property of my user control in the form, the size changes to 150; 150! It seems some how, there is a DefaultValue for Size property. How can I solve my problem? I prefer when I resize my UserControl in form designer, it affects all places it is used. another statement is I want my default size affects from the main UserControl class. Thanks in advance.

    - Signing WinForms ClickOnce app with Certificate Chain Hello all, Now this is a bit involved, so please bear with me :o) I have a Thawte code signing certificate and I am trying to use it to sign C# WinForms project for ClickOnce deployment via the signing screen in VS2008. I was issued PVK and SPC files by Thawte which I used to create a PFX file including the full certification path. The PFX file can then be used with Visual Studio. Thawte use an intermediate certificate for code signing so my certificate is chained to the Thawte root certificate via their intermediate certificate. Creating the PFX file with the full chain embeds the intermediate certificate which is necessary as client machines will only include the root. Our build server includes the full certification chain in its store in order to complete the signing process and performing a fresh install of the built application on this machine correctly shows the 'green tick' for a valid certificate. Unfortunately when I try and perform a fresh install of the click once application on a client machine it shows a 'yellow warning' instead as it is unable to complete the certification path. The machine does not have the intermediate certificate installed but it should be included in the signature. Now, if you check the digital signature for the setup.exe file (right click -> digital signatures) then you can see that the signature is valid and that the certification path is complete, indicating that the certificate included the full path as intended. This leads me to believe that there may be two types of 'code signing' going on, one a 'normal' authenticode type signing and another xml signature of the manifest, that are working inconsistently. It seems that the signature on the setup.exe includes the full chain, but when trying to install the application it indicates the chain is broken. From googling this (see http://www.eggheadcafe.com/software/aspnet/32016113/clickonce-certificate-ca.aspx and http://groups.google.com/group/microsoft.public.dotnet.framework.windowsforms/browse_thread/thread/8c46df2acf25d54/4c1c4221f69fa09e) it looks like this was confirmed as an issue with VS2005 that was intended to be addressed. Any suggestions on how I can get the ClickOnce installation to find the intermediate certificate? Note that getting our clients to install the intermediate certificate as a one-off step is not an option...

    - ContextMenuStrip: ToolStripScrollButton = unrecognized control??? Hi there, I'm trying to create a custom ContextMenuStrip. Everything's (basically) fine, but when the vertical space needed to display all items is less than required, those ScrollButtons show up at the top and bottom of the menu. Digging into how to paint these I found out that these buttons are made up from System.Windows.Forms.ToolStripScrollButton. However, .Net doesn't seem to actually publish these controls. I'd like to: a) paint the background in a different color b) increase the vertical space the buttons are consuming c) paint a border around them While a) and b) are not all too important, I need to somehow draw a border around the buttons. Also, if the ScrollButtons appear, they seem to be drawn over the control AFTER it has been painted. That is, if I paint a border around the menu itself, that border is replaced by the white area of the ScrollButton. Any pointers ..?

If I run it (WinXpProSp2 dotent 2.0), rowheaders are not repainted when vertical scrollbar vanishes, and cells of the last row fills it's area - only cells are moved down and repainted: 'VS2005; Windows Application: datagridview should repaint rowheaders '************************************************************************************ Public Class Form1 Friend WithEvents datagridview1 As New DataGridView Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Controls.Add(datagridview1) Me.Width = 300 Me.Height = 150 Me.datagridview1.Dock = DockStyle.Fill Me.datagridview1.AllowUserToAddRows = False Dim P As Point() = {New Point(1, 1), New Point(2, 2), New Point(3, 3)} Me.datagridview1.DataSource = P End Sub Private Sub MarcinArmedWithMouse(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown 'You can comment this sub and repeat all steps manually...

    - VB low level IO I'm using VB 2005 and want to build and use a counter file. It will be used as an autonumber field for a database application. It will be hit 10 - 15000 times a day. Naturally I want to lock all reads - writes while the number is incremented. The file can be read - incremented and be rewritten. I can cludge something together but I'd like to learn the "correct" method. Thanks Paul Tag: Need example of custom combobox inside DataGridView Tag: 117280

    - Odd runtime error (I've already fixed this. I'm just curious exactly what happened.) I have a Dot Net 2.0 solution with a main winforms project and multiple class libraries. The main winforms project and one of the class libraries both have a reference to an external dll, which is compiled in a separate solution and which I've also been tweaking on recently. It is possible that the 2 projects may have been referencing different versions of the same dll during the time of this problem. What happened was this. The main project calls a method of that class library. That method in turn calls a method of the external dll. Even though everything was compiling normally, the program crashed in the winforms code on the call to the class library, with a MissingMethodException. I was unable to step into the class library's code, even though everything was compiling normally and the method obviously exists. When I detached and reattached the external dll reference in both projects and recompiled, the problem went away. Anyone else ever see anything like this?

    - ClickOnce Start Folder Name keeps getting overwritten Hello, I've figured out how to use Mage to update the manifest to change the name for the Startup folder. However, every time I build the project, this information just gets overwritten again. So for example I want it to be Company Inc and after the build it becomes Company NA. I'm not sure where the NA comes from. I think it comes for the certificate or something, but just don't know. So if someone could enlighten me I would appreciate it.

    - Form Truncation Vertically when shown in a Virtual Machine I have a form that works fine 99% of the time. Occasionally when run in a Virtual Machine (VMWare or Virtual PC) the height of the form is truncated about 8%, hiding buttons at the bottom. The form is FormBorderStyle.FixedSingle, AutoScaleMode=Font, AutoSize=False (not being a Forms expert I'm listing these only because I am guessing they might be relevant). I haven't found any docs or articles describing this, so I'm looking for whatever magic form attribute I need to correct this ;=) . -- Phil Wilson Definitive Guide to Windows Installer http://www.apress.com/book/view/1590592972 Tag: Need example of custom combobox inside DataGridView Tag: 117273

    - Resizing controls embedded in a composite user control I have a composite control consisting of a textbox and label. When i place the custom composite control on a form I would like to allow the user to resize the individual controls within the composite control using the standard drag and alignment hints Visual Studio creates for all of the other Windows controls. I haven't had any luck googling this topic...what is the secret to doing this? Thank you for any assistance, Ron Tag: Need example of custom combobox inside DataGridView Tag: 117271

    - How do I create Forms that behave like the Visual Studio layout? You'll notice that forms in the Visual Studio interface automatically resize when a form is deleted or resized, or when a new form is added. Is there a simple way to accomplish this? (the SplitContainer will not accomplish this behavior). Thanks for your help. Tag: Need example of custom combobox inside DataGridView Tag: 117264

    - Theory question: What sets the default references for a class lib Just noticed this. I'm writing a Winforms VB Dot Net 2.0 app. The app is a solution with a main winforms project and multiple class libraries. By chance I noticed that I was unable to add a user control to one class lib but was able to add it to a new one. The difference was that the newly added class lib had a reference to System.Windows.Forms. The old class lib didn't, even though I've done nothing to change the basic default references set by Visual Studio in this solution. (I'm sure that I did not remove any references to Forms.)

    - How to do single click selection for mousedown in selectionService_SelectionChanged function? Hi, I am creating a custom form designer. In this I am taking a windows form at runtime on which I am droping controls like label, textbox etc. But I am not able to drag these controls anywhere on the form. They ar not getting selected in single click, I have to double click them for selecting. But after doble clicking also they not dragable. On double click it is calling selectionService_SelectionChanged(object sender, EventArgs e) function which is handling events.

    - Beginner questions I'm a beginner in dotnet and I'd like to ask a few questions- 1. What is the advantage of puting some controls on a panel control instead of directly on the form? 2. When I set backgroundcolor and backgroundimage to certain values (to certain color and certain image, respectively of a form) and run it, I see the background color but can't see the backgroundimage. How do I cause it to show-up? 3. I want to choose some kind of control (like picturebox or similar) in order to display different view in different times, i.e images, real-time video(with directx) etc. It should support most of the methods for that. Can someone recommend what is the most suitable? Regards Rami Tag: Need example of custom combobox inside DataGridView Tag: 117252

    - Crystal Reports and Winforms Has anyone suceessfully done the following? I have a winfroms app that displays a cr viewer on a form when the user wants to view a report. The viewer loads up the report dynamically. I don't compile the report with the app. And then displays the app after setting any passed parameters the datasource and so forth. 90% of the time it works great. The other 10% of the time, the viewer seems to be hidden in the background doing something and I have to alt tab to another window and back to display the viewer and the report. I am wondering if I can't bundle the viewer with the app and have to have a separate viewer running on the client machine to be called and display the reports. For those of you who have done something like this. Should I take the viewer out of my app and make a separate app for the viewer and when the user wants to run a report load the viewer as a dll into memory pass it the parameters needed and then display the report.

    - Plugin architecture Hi Is there a way to write a "plug-in" that can be used with both a winform app and a windows service? If so, how? Thanks Regards Tag: Need example of custom combobox inside DataGridView Tag: 117249

I'm looking for a tutorial, example, or source code sample which shows how to
host a custom ComboBox control inside a DataGridView.

In other words, I have a new control "MyComboBox" which inherits from
ComboBox, then I create a an EditingControl for this class, which implements
IDataGridViewEditingControl, as well as associated classes which inherit from
DataGridViewComboBoxCell and DataGridViewComboBoxColumn.

I have my code basically working, with the following exceptions:
- the displayed text being shown after a selection is made is not correct
- the initial drop-down is not entirely shown correctly, but all subsequent
drop-downs are

Anyone with suggestions or (better yet) a sample of how to do this would be
great!
